The front side of the interior vertical wall 8 is in an openv state for receiving a interior vertical a space 11 for detachable insertion of a bedpan being formed between the upperwall 9 and the front edge portion of the bottom plate that is enclosed by the exterior vertical wall and the interio vertical wall, the peripheral edge of the well 10 in the upper wall 9 projecting over said space 11 in the shapeof a flange.

On the front peripheral edge of the bottom plate 2 is continuously formed a projecting wall 12 projecting to a required height, each end of said projecting wall 12 reaching the exterior vertical wall thereby preventing leakage from the surface of the bottom plate 2.

Moreover, the bedpan 13 is of such size that said bedpan 13 is detachably insertable into the space 11 of the buttocks rest 3 on the bottom plate 2 of the buttocks seat 1, said bedpan 13 being formed in the shape of a hollow vessel as shown in FIG. 4 by means of the blow molding method or the like making use of a synthetic resin. The upper wall of said bedpan has a front part that is a tier lower, said lower front part being provided with an opening 14. The opening 14 is adapted to be positioned precisely under the well 10 of the buttocks rest 3 when inserted into the space 11 of said buttocks rest 3, saidopening being oval in shape. A handle 15 is erected on the upper surface of the basal end portion of the bedpan.

In addition thereto, a projection 16 is erected on each side of the midway portion of the upper surface of the bedpan l3. Said projections 16 are provided with the object of positioning the bedpan 13 so that the opening 14 thereof is positioned precisely under the well 10 of the buttocks rest when said bedpan 13 is inserted into the space 11 of said buttocks rest. Therefore, said projections 16 are adapted to have a height sufficient to come into contact with the front edge of the buttocks rest.

A holder 18 ofa fixing member 17 of a urinal pad is erected on each side of the upper surface of the bedpan adjacent the basal end thereof. Said fixing member 17 comprises wire, such as piano wire and the like, said wire being bifurcated into an upliftable lever 19, an openable clip 20 equipped with a built-in spring being mounted at the front end of said lever 19. A bend is provided at each end of the upliftable lever 19, said bend being fitted into a transverse hole 21 of each holder 18.

Said bends are given an outwardly extending force prior to insertion into the transverse holes of the holders 18 thereby enabling the upliftable lever 19 to be halted at any required uplifted position.

The upliftable lever 19 is provided with a clip 20 at the front end thereof, said clip 20 securing the upper edge of a urinal pad 22 comprising paper, a synthetic resin sheet or the like, said urinal pad 22 covering the part between the thighs of an invalid lying on the buttocks rest 3. Furthermore, said urinal pad 22 not only prevents the urination of the invalid from splashing about, but also helps said urination flow into the bedpan guided by the urinal pad since the lower edge thereof is inserted into the opening 14 of the bedpan 13.

The toilet utensil for invalids according to this invention comprises a construction as described hereinbefore, and the use of said toilet utensil is explained hereinunder.

When an invalid wants to urinate or defecate, a nurse inserts a buttocks seat 1 under the buttocks of the in valid from between the opened thighs of said invalid in a state wherein said buttocks are slightly uplifted.

Then, when the buttocks of the invalid settles on the inserted-buttocks rest 3 of the buttocks seat 1, an independent bedpan 13 is inserted into the space 11 below the buttocks rest 3 in a state wherein the urinal pad fixing member 17 is uplifted. If the bedpan 13 is inserted until the projections 16 come into contact with the buttocks rest 3, the opening 14 of the bedpan is positioned precisely under the well of the buttocks rest 3 as shown in FIG. 2.

In this state, the upper edge of the urinal pad 22 is folded back and inserted into the clip 20, the lower edge thereof being left to hang down into the opening 14 of the bedpan, said urinal pad 22 being arranged to cover the part between the thighs of the invalid. The urinal pad 22 is adjustable by adjusting the angle of the upliftable lever 19 as shown in FIG. 1.

Evacuation is received in the bedpan the well 10 and through the well 10 and the opening 14, urination being also received in said bedpan l3 guided the'uiiifii pad 22.

After the evacuation, the bedpan 13 is removed by drawing it out, the buttocks seat being then drawn out while the buttocksof the invalid are slightly uplifted. The urinal pad 22 is removed by releasing the clip 20, the evacuation together with said urinal pad received inside the bedpan being suitably disposed of.

As described hereinbefore, the toilet utensil for invalids according to this invention comprises a leakproof bottom plate 2, a buttocks seat 1 on said bottom plate 2, provided with a buttocks rest 3 having a space 11 for inserting a bedpan thereinto, and a bedpan 13 detachably insertable into said space 11 of the buttocks seat 1, each said member being formed by means of the blow'molding method or the like making use of a by a resin, with the result that the toilet utensil of this invention can be provided at a moderate price since said toilet utensil is producible by a very simple process and on a mass production basis, a further advantage being that said toilet utensil is very convenient not only for use for invalids but alsofor transportation because of the light weight thereof.

Furthermore, the toilet utensil of the invention enables an invalid to use it not only in a state of lying on his back which is the most comfortable posture for the invalid, but also in a state of lying on his right or left side, as a result of which the toilet utensil of this invention releases invalids and nurses from the greatest inconvenicences otherwise experienced by both said parties.

Since the toilet utensil of this invention prevents the buttocks of an invalid from coming into direct contact with the bedpan, not only evacuation can be effected comfortably without any sense of filth but also the evacuation is disposable sanitarily. Moreover, since a urinal pad fixing member is mounted on the bedpan insertable under the buttocks rest, the part between the thighs of an invalid can be covered with a member comprising paper, a synthetic resin, or the like, with the result that urination arising with evacuation can be directed into the bedpan by means of said urinal pad. Thus, the toilet utensil of this invention has a distinct advantage in that said toilet utensil prevents the bedclothes from being soiled by spilled or splashed urination, the leakproof property of the bottom plate 2 further ensuring sanitariness of said toilet utensil.
